People with lower blood sugar levels are more likely to have better scores on the memory tests.

Even for people who do not have diabetes or high blood sugar, those with higher blood sugar levels are more likely to have memory problems, BBC health reported.

According to a new study in American Academy of Neurology, this was proved after studying tests of 141 people with an average age of 63 who did not have diabetes or pre-diabetes.

The participants’ memory skills were tested, along with their blood glucose, or sugar, levels. Participants also had brain scans to measure the size of the hippocampus area of the brain, which plays an important role in memory.

People with lower blood sugar levels were more likely to have better scores on the memory tests. On a test where participants needed to recall a list of 15 words 30 minutes after hearing them, recalling fewer words was associated with higher blood sugar levels.

These results suggest that even for people within the normal range of blood sugar, lowering their blood sugar levels could be a promising strategy for preventing memory problems and cognitive decline as they grow older.
